On patrol - Fish Rock Cave, NSW

Fish Rock Cave is a spectacular dive, culminating in this exit into the blue with patrolling Grey Nurse Sharks. Grey Nurse Sharks have been described as the world's scariest harmless shark, as while they have viscious looking teeth, they use these to grab hold of fish and then swallow them whole. Fortunately, we're far too large for them to have a go at us and we're not on the menu!
